The normal aortic valve, on the axial thin-section images that are reconstructed from the raw data (usually 1mm at 0.5mm intervals) shows a very typical appearance (Fig. 1). The three cusps form a "Y", the sinuses forming a clover-leaf appearance. In the absence of this appearance, a bicuspid valve can be easily diagnosed (Fig. 2).
This was a 41-years old asymptomatic man who had come for a cardiac CT. His coronary arteries were normal (Fig. 5). The bicuspid valve is also well seen in the transaxial view (Fig. 3). He also had dilatation of the ascending aorta. He refused an echocardiogram at the time, but promised to get it done in his own town. We still don't have the follow-up result though.
